Explore removing compiled JavaScript from repo

[stuartleeks]

In the current implementation, the ci action is referenced with tags that pull the main repo code. As a result, the compiled JavaScript needs to exist in the repo. However, this adds a required (local) build step when making changes and increases the number of conflicting changes across PRs.

The action for publishing dev container features uses https://github.com/JasonEtco/build-and-tag-action in the publishing step.

From a quick scan, this packages a compiled version of the code under the tag. If the same approach can be used here this would allow removal of the compiled output.
